(620 ILCS 25/16)(from Ch. 15 1/2, par. 48.16)Sec. 16. Airport zoning regulations to effectuate airport approach plans. Every airport zoning regulation for an airport hazard area existing in
connection with a publicly-owned airport shall be designed to effectuate
the Department's airport approach plan, as amended by it, whenever
necessary, for such publicly-owned airport. Upon complaint filed with the
Department, including a complaint upon the Department's own motion, and
after notice and opportunity to be heard, in the manner provided by "An Act
relating to aeronautics and repealing a certain act herein named", enacted
by the 64th General Assembly, if the Department determines that any such
airport zoning regulation, in whole or in part, is substantially
inconsistent with the airport approach plan of the Department, as amended
by it, whenever necessary, it shall declare such airport zoning regulation
to be void, in whole or as to any separable part thereof, as may be
appropriate, and the whole or such separable part of such airport zoning
regulation as was declared by the Department to be void shall thereafter be
deemed to be void.(Source: Laws 1945, p. 317.)
